Hello, i'll be discussing about on how to get that trust factor UP! Not going to lie and just tell you the truth!
Getting Trust Factor Up on a new account that has NOT played CS:GO is incredibly hard.
1. Steam Level : Make sure that you have a Level of over 10 it does increase a slight trust factor
2. Have an open profile!
3. Having a lot of hours in CS2 will help a lot !
4. Try avoiding griefing or being toxic : If you get reported or got a timeout, it will lower the trust factor.
5. Some people have said that getting a global cool down, will reset you're trust factor to default. (I DO NOT CONDONE PLAYING WITH CHEATERS TO GET THE GLOBAL COOL DOWN)
6. It is a MUST that you have spent money on the game itself, if you got prime for free, then proceed with spending at least 5$
7. Have a steam guard
8. Have at least the maximum of friend's that you can have [Every 1 Level = 5 friend slots] Make sure that they are not cheating and will not be banned
9. Join some groups!
10. Make sure that you're email is verified and have at least a phone number on the steam account!
11. Try avoiding on kicking players that are having a difficult time, it can lower the trust factor due to kicking too many players (You can get a cool down for either kicking players or getting kicked too many times)
12. Up voting / Giving awards to Guides / people , does help as well, cause it shows that you are an active member of the CS community.
13. Getting comments under steam and awards!
14. Of course playing without cheats! (You can get reported and the trust factor will go down + you are hurting the CS community by not playing fair!)
15. Avoid playing in a stack with cheaters (It can result in a vac live and you can lower the trust factor just like that)
16. Getting commendations, it does help a bit, but buying commendations will not help, it depends on the hours you have and how many you've gotten within the hours you have collected.

If you think this guide helped you please if you can Up vote it and give it a small award, id appreciate it a lot :3
Will post more in the future if i have found out anything.
ill gladly help anyone out if you have any questions!
